Kev piav qhia:

Ncaj seam siab zaus (ERW) tau muab faib ua ob hom: induction vuam thiab tiv tauj vuam raws li txoj kev sib txawv vuam. Nws siv kub dov dav coils raws li raw cov ntaub ntawv thiab undergoes pre-bending, nruam forming, vuam, kho cua sov, sizing, straightening, txiav, thiab lwm yam. uniform phab ntsa thickness, zoo nto zoo, thiab siab kub kuj. Txawm li cas los xij, qhov tsis zoo yog tias nws tsuas tuaj yeem tsim cov kav dej nyias nyias ntawm cov kab me me thiab nruab nrab, thiab cov pob grey thiab tsis muaj fusion yog qhov tshwm sim ntawm cov welds. , Groove corrosion tsis xws luag. Tam sim no, cov chaw siv dav tshaj plaws yog lub nroog roj av, roj av thiab cov roj ua kom zoo dua qub, thiab lwm yam.

Ncaj seam submerged arc (LSAW) yog tsim los ntawm kev siv ib qho nruab nrab-tuab phaj raws li cov khoom siv raw, nias (rolling) steel phaj hauv pwm los yog lub tshuab tsim, thiab siv ob sab submerged arc vuam thiab txoj kab uas hla. Nws cov khoom tiav specifications yog dav, lub toughness, plasticity, uniformity thiab ceev ntawm cov weld yog zoo, thiab nws muaj qhov zoo ntawm cov yeeb nkab loj txoj kab uas hla, tuab yeeb nkab phab ntsa, siab kub tsis kam, tsis kub tsis kam thiab muaj zog corrosion kuj. Thaum tsim kom muaj lub zog siab, siab tawv, thiab cov kav dej ntev ntev thiab cov pa roj zoo, feem ntau ntawm cov kav hlau uas xav tau yog qhov loj-inch, tuab-walled ncaj seam submerged arc kav. Raws li API cov qauv, hauv cov kav dej loj loj thiab cov kav xa hluav taws xob, cov kav dej sib txuas ncaj nraim yog tib txoj kev tsim cov yeeb nkab uas siv tau thaum dhau ntawm Chav Kawm 1 thiab Chav Kawm 2 xws li thaj chaw alpine, seabed, thiab cov neeg nyob hauv nroog loj.

Raws li kev sib txawv molding, nws tuaj yeem muab faib ua:

UOE steel yeeb nkab: Tom qab ib lub phaj steel yog pre-khoov ntawm ntug, nws nkag mus rau cov txheej txheem xws li U forming, O forming, internal welding, sab nraud welding, thiab mechanical txias expansion.

JCOE steel yeeb nkab: uas yog, pre-welding, tsim, thiab txias expansion tom qab vuam raws li "JCOE"

HME steel yeeb nkab: tsim los ntawm mandrel dov txoj kev raws li "CCO", welded thiab ces txias nthuav.
